Core and core drills

Crown drill / puncher / drill bit bi-metal, jigsaw Average: according to the selected variant Max. drilling depth: 38mm Catalog number: 20.1500 Cutting conditions - see attached catalog sheet Material: HSS Co8 (high speed steel with 8% cobalt) Fine tooth - toothing 4/6 " Suitable for drilling in: alloy and common steels, stainless steel, non-ferrous materials and light metals * From a diameter of 160 mm, drilling into metal is not recommended - only non-metallic materials, wood, plastic, etc. HSS Co8 bimetal jigsaw. Fine gearing is very well suited for metals. It ensures a quieter operation and requires less effort. Due to less heat generation during cutting, the service life is extended, especially for metals. Suitable for alloy and common steels (up to 750N / mm2), high chromium steels such as stainless steel, acid-resistant steels, non-ferrous materials and light metals.

Crown drill / puncher / drill bit bi-metal Average: according to the selected variant Max. drilling depth: 38mm Cutting conditions - see the enclosed catalog sheet Suitable for drilling in: non-alloy steel, non-ferrous and light metals, plastics, plasterboard, reinforced boards, plywood and woodworking HSS bimetallic jigsaws with variable gearing. For easy-to-machine materials, the variable toothing ensures a more even tool passage and requires less effort. Thanks to lower vibrations and heat generation during cutting, up to three times longer service life is achieved. Suitable for non-alloy steels up to 700N / mm2, non-ferrous and light metals, plastics, plasterboard boards, reinforced boards, plywood and for working with wood.

Cobalt core drill / jig / drill bit bi-metal Average: according to the selected variant Max. drilling depth: 38mm Cutting conditions - see the enclosed catalog sheet Material: HSS Co8 (high speed steel with 8% cobalt) Fine tooth Suitable for drilling in: alloy and common steels, stainless steel, non-ferrous materials and light metals HSS Co 8 bimetal jigsaw. Fine gearing is very well suited for metals. It ensures a quieter operation and requires less effort. Due to less heat generation during cutting, the service life is extended, especially for metals. Suitable for alloy and common steels (up to 1100N / mm2), high chromium steels such as stainless steel, acid-resistant steels, non-ferrous materials and light metals.

Carbide core drill / puncher / drill bit is made of one piece - including shank. Diameter: according to the selected variant (average tolerance 1mm) Drilling depth: 25mm It has powered carbide teeth, which allow easier drilling with less pressure force. Precise guidance is ensured by a removable guide drill with a diameter of 6 mm. The spring on the drill bit is used for easy removal of the drilled material. The guide drill is secured with an Allen key. The drill has a ground surface. The teeth are 3 mm wide, which ensures more economical drilling. The clamping shank is adapted for clamping in a three-jaw chuck. Application: Column drill , or hand drill with drills up to a diameter of about 40-50 mm - but it is necessary to keep the drilling axis and always keep all the cutting edges in engagement. If you do not keep all the blades in engagement or you are not able to keep the drill in the drilling axis (jerks, shocks, etc.), the carbide blade may be chipped - ie irreversible damage to the tool.

Jigsaw - core drill for magnetic drill Crown diameter: according to the selected variant Recommended drilling depth - max 25 mm Welding shank - 19 mm (3/4 ") Centering pins (see related products): For diameters 12-60mm: 20.1221 Material - HSS-XE - special high-alloy steel Tooth hardness: 68HRC Catalog number: 20.1255 These core drills are made of special high-alloy steel HSS-XE, which ensures extreme hardness at the tips of the teeth (up to 68 HRC), high wear resistance and long service life. Few manufacturers are able to produce HSS core drills hardened in several stages. This is standard for Karnasch®. This is the only way to get extremely hard tooth tips (68 HRC) and a flexible and durable drill body. For HSS-XE / ASP core drills, five different drill geometries are applied for different drilling diameters and depths, so that the result is always perfect.
